  The present invention relates to the field of high precision mechanisms for watches or scientific instruments, and more particularly to the field of adjusting the operation of such mechanisms.

  In order to adjust and adjust precision mechanisms such as timepieces and scientific instruments, it may be necessary to geometrically adjust very small amplitudes, on the order of a few micrometers or at most a few hundredths of a millimeter. is there. Such adjustments are already a matter of caution, even in instruments with considerable dimensions, such as micrometer stops used in precision mechanics or control rooms, and the dimensions of watch parts are reduced. Therefore, it becomes difficult to perform fine and accurate adjustment.

  Such final adjustment is an exclusive area by highly competent professionals and is responsible for the product being in a certain price range.

  For example, in a mechanical timepiece, the balance spring oscillation can be maintained by a Swiss ankle speed control mechanism. The amplitude of the balance is determined by the energy delivered. If the amplitude is too small, the quality of operation is degraded, and if the amplitude is too large, knocking occurs. It is therefore necessary to make final adjustments to correct the placement of the ankle and the output stones in order to obtain optimal operation. This modification requires removal of the ankle, balance and corresponding bridge, and this operation must be repeated until the desired amplitude is obtained. This also requires very high costs.

  When casting an ankle as a single part from silicon, plastic material, etc., the pallet cannot be adjusted and the balance of the balance cannot be adjusted effectively.

  In Patent Document 1 by MATEY, it is described that the escapement bridge is pivoted under the direct action of a screw to correct the distance between the escapement shaft and the ankle shaft.

  U.S. Pat. No. 6,057,038 by TAVANNES WATCH CO SA emphasizes the high cost of adjustment changes and the need to maintain parallel relationships between different wheel axes. Patent Document 2 discloses an eccentric part that cooperates with a slot of a lever to displace a shaft.

  U.S. Pat. No. 6,057,031 to EBOSA SA discloses a simplified direct contact solution that does not require fine tuning. Adjustment can only be made in one direction. This document teaches the use of a deformable bridge with direct support of screws. Similarly, U.S. Patent No. 6,053,077 to LIP SA discloses wheel shaft displacement control with a deformable bridge or lever or bolt. As of 1960, Patent Document 4 describes problems relating to interference in adjustment and the cost of adjusting the function of the escapement function of the movement.

  The present invention relates to the field of high-precision mechanisms for watches or scientific instruments (hereinafter both referred to as “clock mechanisms”), and more particularly, the performance of these mechanisms, particularly during operation, In the field of adjusting the operation of such a mechanism when it relies on the adjustment at the micrometer level of the position and / or geometry between the various wheels forming the wheel.

  The field of inclusion is limited to such limited adjustments, referred to herein as “at the micrometer level”, ie the amplitude is limited to a few micrometers or even a few tens of micrometers. The

  The invention relates to a local geometry correction or the position of at least one end of one of the wheels forming part of this mechanism with respect to the position and / or pivoting direction of the other wheel of the mechanism in question, or It is proposed to create a means for adjusting the performance of the watch mechanism by modifying the local geometry of the wheel axis position.

  Based on this, the present invention relates to a micrometer level displacement mechanism that can be adapted to a small space available in a small mechanism such as a timepiece, particularly a wristwatch. In practice, the micrometer level displacement mechanism is preferably designed so that the micrometer level displacement mechanism always remains in place within the mechanism that assists in the adjustment.

  The invention thus relates to a mechanism 1 for micrometer level displacement of at least one guide element 10 for a watch wheel belonging to the same watch movement relative to a reference axis of the watch movement. The micrometer level displacement mechanism 1 comprises means for displacing the at least one guide element 10 relative to the reference axis.

  According to the invention, these displacement means are micrometer level displacement means 30 controlled by adjusting means 40 which are offset relative to the reference axis and to the theoretical position of the at least one guide element.

  In a preferred manner, the adjusting means 40 adjusts the path limited to the first adjusting amplitude and comprises an amplitude reducing means 50, which is less than the adjusting path transmitted to the adjusting means 40. An adjustment path having a smaller and proportional amplitude is transmitted to the guide element 10. Then, the amplitude reducing means 50 transmits this adjustment path to the guide element with an angular dispersion of less than 1.0 ° with respect to the reference plane. The reference plane passes through the reference axis, and the reference axis and the first fixed axis. It occupies a predetermined angular position with respect to the plane formed from DP1.

  More particularly, the micrometer level displacement mechanism 1 relates to the displacement of a first watch wheel forming part of the watch mechanism relative to at least one reference watch wheel defining this reference axis.

  The guide element 10 can be male or female when rotated in order to receive the guide surface of the first wheel.

  Also preferably, these amplitude reduction means 50 are arranged to convert this adjustment path into adjustment paths in various directions.

  According to a feature of the present invention, these micrometer level displacement mechanisms 30 comprise levers 37 that form these amplitude reduction means 50. The lever 37 pivots around the first fixed axis DP1. The lever 37 is provided with a first support arm 36 and a second control arm 39 which are carriers or drivers of the guide element 10 on both sides of the pivot 38 at the height of the fixed shaft DP. The adjusting means 40 comprises an eccentric finger 41, which can be pivoted about the second fixed axis DP2 of the slot 42 of the second control arm 39, whereby a second around the pivot 38. The control arm 39 is pivoted. The value of the maximum displacement range of the eccentric finger 41, the ratio of the length between the second control arm 39 and the first support arm 36, and the apex angle of these two parts with respect to the pivot, all of the guide element 10 The maximum adjustment range is determined. The eccentric finger 41 can also be moved by a tool engaged in the slot or by a toothed system integrated with the finger 41, and the finger 41 can be connected to a roller at the periphery of the plate by a gear train or the like. it can.

  For example, in a mechanism similar to the mechanism of FIG. 1, in the vertical lever 37, the first support arm 36 having a length of 4 mm, the second control arm 39 having a length of 8 mm, and the height of the finger 41 of 0. With a combination of 080 mm eccentric paths, the entire guide element 10 path is 0.040 mm, following a trajectory deflecting less than 0.2 μm on both sides of the median plane with a total angular dispersion of about 0.6 °. Thus, in this configuration, the adjustment can be considered to be performed in a substantially planar manner.

  In the embodiment of the present invention, which is the simplest to implement due to the unidirectional nature, these displacement means 30 displace only one end of the first wheel and hold the other end of the first wheel in a fixed position. It has been done.

  In another embodiment not shown, the displacement means 30 displaces the first wheel parallel to the reference axis of the reference wheel. Such a connection can be made while being controlled using a single adjusting means 40 by means of a connecting part comprising two levers 37 connected to both sides of the first wheel.

  According to another characteristic of the invention, the micrometer level displacement mechanism 1 also comprises means 32 for holding the position of the guide element 10 after adjustment. In a particular configuration, these means 32 for maintaining position comprise at least one spring 33.

  The present invention also relates to a timepiece mechanism 100 comprising at least one reference timepiece wheel defining a reference axis and a first timepiece wheel, wherein at least one end or at least one guide surface of the first timepiece wheel is thus The micrometer level displacement mechanism 1 is used to adjust to a predetermined position with respect to the reference axis, and the first fixed axis DP1 is held at a fixed position parallel to the reference axis.

  In certain embodiments, the watch mechanism 100 comprises at least two reference watch wheels, each defining a reference axis and together defining a reference plane. The micrometer level displacement mechanism 1 then displaces at least one such guide element 10 on a plane substantially passing through one of these reference axes and with a predetermined orientation relative to this reference plane. To be arranged. For example, FIG. 1 illustrates the case where adjustment of the position of the guide element 10 is achieved on a plane substantially passing through two reference axes D1 and D2.

  The present invention will be described below with respect to a preferred application to the speed governing mechanism 100, but this is not restrictive at all.

  In particular, the present invention will be described with respect to a preferred configuration of a straight escapement in which the center of the escape wheel, the ankle and the balance are arranged in a straight line, which is generally a Swiss ankle as shown in FIG. This is what is seen in escapements.

  A watch designer who wants to adjust the operation of a particular speed control mechanism, such as a mechanism in which the shafts are not all on the same plane, can be controlled by a local displacement of at least one end of the wheel or a local displacement of the entire wheel. It is clear that it can be understood how the present invention can be used by inferring from the behavior described here, intentionally the simplest case, in order to optimize.

In this particular application, the invention is
An escape wheel shaft 2 with an escape wheel shaft 3 having an axis D and drive means 4 such as an escapement pinion;
An ankle 5 comprising an ingot meteorite 6 and an exit meteorite 7, an ankle pivot 8 around the ankle pivot axis, a fork lever 9, and a fork 12 having a guard pin 13; The displacement is limited by the blocking means 11 such as a blocking pin, an ankle 5;
A balance 15 with a balance 15 around the balance axis, at least one notch 16 at the height of the small disk 17 or structure of the balance 14, and at least one disk pin 18 at the height of the large disk 19 or structure of the balance 14; A balance 14, wherein the balance 14 is arranged for fixing at least one spring 20;
The axis D1 of the ankle pivot 8 and the axis D2 of the crown 15 are parallel on a common plane P, and the axis D1 of the anchor pivot 8 and the axis 15 of the crown 15 are in a common vertical plane P1. An escapement line E is defined that connects the axis D2 with an extension of this plane P1.

  The ankle speed adjusting mechanism 100 is a displacement means for displacing at least one end of the escape wheel shaft 3 according to the configuration shown in FIG. 4 or for displacing the axis D of the escape wheel shaft 3 according to the configuration shown in FIG. A micrometer level displacement mechanism 1 is provided. These displacement means 30 use at least one component force in the plane P defined by the axis D1 of the ankle pivot 8 and the axis D2 of the balance 15 and preferably substantially in this plane P, ie the plane P The guide element 10 is arranged to be displaced by using a component force perpendicular to the plane P that is less than 1% of the value of the component force along. As mentioned above, the dimension of the displacement means 30 is such that the component force perpendicular to the plane P is minimal with respect to the component force in the plane P, ie less than 0.5% in the example outlined above. Calculate as follows.

  Preferably, the guide element 10 is formed from a jewel 34 or a bearing.

  In a particular configuration, the displacing means 30 is arranged to effect displacement only in a plane P defined by the axis D1 of the ankle pivot 8 and the axis D2 of the balance 15.

  According to the features of the present invention, these displacement means 30 displace only the one end 31 of the escape wheel shaft 3, as shown in FIG. This end 31 preferably faces the escapement pinion 4 which normally works with the fourth wheel. The +/− 20 micrometer path at the height of the end 31 does not impair the quality of the gear meshing at the height of the fourth wheel.

  According to another feature of the invention, these displacement means 30 also comprise means 32 for holding in place after adjustment in the position of the escape wheel shaft 3. In certain embodiments, the means 32 for holding in place comprises at least one spring 33. This spring 33 in particular ensures that play is maintained in the direction of the axis D.

  According to another particular preferred embodiment of the invention, the displacement means 30 causes the end 31 of the escape wheel shaft 3 or the axis D of the escape wheel shaft 3 to be moved to the theoretical position 310 of this end 31 or this axis D. Can be displaced with an amplitude of about 20 micrometers with respect to the theoretical position D0. This value is sufficient to optimize the operating parameters without compromising the quality of the gear meshing. According to the records, the loss of concentricity when driving in the gemstone is 2-4 micrometers.

  Such a modification of the micrometer level displacement mechanism 1 to obtain different adjustment ranges is simple because it is sufficient to work on the eccentricity of the eccentric finger 41 and / or the length of at least one of the lever arms. It is.

  As shown in FIGS. 1 to 5, the displacing means 30 preferably comprises a lever 37 and is arranged to displace at least one jewel 34 disposed in the gap 35 of the support arm 36 of the lever 37. In the particular configuration of FIG. 1, the lever 37 pivots about a pivot 38 and includes a control arm 39. This control arm 39 is movable by the action of the adjusting means 40. The lever 37 preferably has friction at the height of its pivot 38, for example by using a split pivot or the like. In this same configuration of FIG. 1, the adjustment means 40 comprises an eccentric finger 41 that pivots about an axis 44 having a rotating shoulder 46, having an eccentricity “e” around the axis 44 and controlling. The arm 39 pivots in a guide 441 that controls the pivot of the control arm 39 in cooperation with a track 42 (here in the shape of a groove). The eccentric finger 41 is preferably held at a predetermined position by friction 43 by, for example, a lock washer. Friction can also be ensured using the split eccentric finger 41, where firm retention in the groove 42 is ensured by elasticity at the height of the slit. This friction on the height of the finger 41 must maintain a smaller load moment than the friction at the pivot of the lever 37. In a modified example, holding in a predetermined position after adjustment can be performed by adhesion, application of a small amount of varnish, laser micro welding, or the like.

  The application example of the present invention using the speed control mechanism can correct the adjustment of the pallet stone by correcting the entire lock and distributing the chronic error over each of the entering pallet and the excavated pallet. ,Interesting. Therefore, in the present invention, the ankle can be used as before without correcting or removing the ankle.

  The present invention can also be applied to escapement modules that are formed only from ankles and balances and have no escape wheel, as in some module designs.

  Of course, since the present invention seeks to provide micrometer level adjustments, the micrometer level displacement mechanism 1 must be carefully operated and all adjustments must be performed without play. Don't be.

  In another variant of the invention, the displacement means 30 of the axis D of the escape wheel shaft 3 comprises a guide element 10 formed from a plate 60 or a bridge, or a part of this plate or bridge, i.e. a jewel 34 or the like. It consists of a means for displacing with respect to the support body 61 to carry. The support 61 is designed to be sufficiently rigid so that it does not impair the dispersion of stresses applied to the jewel 34 during driving or operations performed on the support.

For this purpose, the support 61 can be configured in two different ways:
In a manner that has been removed from the plate 60 or the bridge, guided by the guide means 62 and adjusted using the adjustment means 65, in which it is necessary to make micrometer level adjustments and therefore adjustments The path needs to be limited to very low values, especially an amplitude of 40 micrometers, resulting in a very costly and complex layout; or
-Forming one part of this plate 60 or this bridge, delimited by a deformable region 68 having a smaller cross section than this support 61, on the other hand, forming the rest of the bridge or plate 60 structure. Thus, the deformable region 68 can be stressed at the micrometer level while maintaining the functional region, particularly the quality of the rigidity of the pivot holder. Since the adjustment amplitude is small, the deformable region 68 itself can be made small.

  In the particular configuration shown in FIGS. 8 and 9, the plate 60 or bridge comprises at least one deformable region 68, where each comprises one or more grooves 69 and is delimited by the grooves 69. Two deformable regions 68 are provided. Each deformable region 68 separates the rigid support region 61 of the jewel 34 from at least one peripheral region 60A, which is also rigid. All the peripheral regions 60A are assembled to the structure of the movement 200 or the timepiece mechanism 100, that is, the stationary position of the plate or the like by fixing means (not shown) such as screws. FIG. 8 shows a design aimed at unidirectional adjustment, which gives good results for dynamic adjustment and is also reversible and reproducible. Advantageously, the peripheral region 60A, the deformable region 68, and the support region 61 for holding the jewel 34 are aligned in the same plane, for example by two rods 63, on the rod 63 the deformable region 68 and the support region. 61 slides at the height of the gap 64, and the rod 63 is held on the peripheral region 60A by clamping, bonding, welding, soldering or the like.

  Each peripheral region 60A includes adjusting means formed, for example, from a mounting screw 66, and this adjusting means rests against the first partition of the deformable region 68 facing the peripheral region 60A. Advantageously, the deformable region 68 is configured like a bellows with a thin walled partition. The deformation due to the spreading of the first partition and the entire deformable region is a deformation having a smaller amplitude than the deformation generated by the mounting screw 66 and applied to the support region. Each mounting screw 66 can be adjusted after an amplitude limit selected by adjusting the theoretical value of the position of the support area or the position of the escape wheel pivot, for example 20 micrometers after the theoretical position of each of the two mounting screws 66. . The adjustments made can be fixed by permanently fixing the mounting screws in place, for example by laser welding, adhesion or the like.

  FIG. 10 shows that an eccentric finger 71 having an eccentricity “e”, which can be connected to each other by means of a connecting rod 72, rests on the peripheral edge 73 of the deformable region 68, allowing very fine adjustments. A modification is shown.

  According to another variant of the invention shown in FIGS. 11 and 12, the displacement means 30 of the escape wheel shaft axis D comprises a bridge with an eccentric finger 71, which is in relation to the spring element 75 in the guide 74. Limited movement. This spring element is held on the plate 60 by a pin 76 or the like. As is apparent from FIG. 12, the eccentric finger 71 can be pivoted using a toothed system 77. However, in this variant, the displacement of the axis occurs not only on the plane defined by the ankle pivot axis and the true axis, but also in a limited space around the theoretical position of this axis.

  14-18 show another embodiment of the present invention. The guide element 10 is inserted into a frame 80 that performs the same function as the support 61 in the embodiment of FIGS. The frame 80 is an integral part of the plate 60 or bridge of the watch movement 200, and the frame 80 is separated from the plate 60 or bridge by one or more grooves over most of its periphery, and at least one pin Alternatively, it is connected to the plate 60 or the bridge by one or more deformable arms 81 by the action of pressure applied by screws or corners or the like. FIG. 14 shows a symmetrical configuration with respect to the plane containing the axes D1 and D2, in which the axis D of the guide element 10 is aligned with respect to the axes D1 and D2, where in a preferred application to the escape wheel these axes Are the ankle shaft D1 and the balance shaft D2. FIG. 15 shows a similar arrangement, but here the frame 80 is connected to the plate 60 by a single arm 81, which is not symmetrical, but is advantageous because it occupies a smaller surface on the plate. FIGS. 16 and 17 show a non-limiting application based on FIG. 15, in which at least one pin 84, 85, 86 having a cross section larger than the local width of the peripheral groove 82 is clamped in this groove 82. Has been. By inserting this pin, the corresponding arm 81 is deformed, whereby the axis D of the guide element 10 is displaced. FIG. 16 shows the pin 84 in place, followed by, for example, another pin 85 or other side by side, which is generally between the arm 81 and the rest of the plate 60. It can be considered that all straight gaps are filled by a continuous pin, wedge or the like or by a single corner or wedge having a length corresponding to this part. FIG. 17 shows a pin 86 having a diameter Φ2 that is larger than the diameter Φ1 of the pin 84 of FIG. 16, and the deflection E2 between the axis D0 and the axis D1 is larger than the corresponding deflection E1. Various geometries are conceivable depending on the desired displacement to be transmitted to the axis D. Thus, FIG. 18 shows a crossed-out geometry that allows displacement along two orthogonal axes. This figure shows a notch 83 corresponding to a predetermined pin arrangement. By using such a separate position associated with a pin of a predetermined diameter, the value of the axis D of the guide element 10 can be displaced by a predetermined value with reference to a simple chart.

  FIG. 19 shows the configuration with parallel grooves 82 in a free state, where the groove edges 87 are parallel to the arm edges 88 except for the notch region 83. This figure shows the deflection of the arm 81 due to pin support in response to the positioning of the same pin 84, which here shows three positions 84A, 84B, 84C. If the assembly formed from the arm 81 and the frame 80 is considered substantially rigid, the center of the guide element 10 is relative to the rest position with the abscissas for the sides EXA, EXB, EXC and the side EYA. Occupies axes DA, DB, and DC located as ordinates for EYB and EYC. If the deflection angle is very small, these deflections of the ordinate position are very small relative to the deflection of the abscissa position and have no special influence on the operation. The limitation on the use of the pin is determined by the contact between the frame 80 and the groove edge 87 and of course the rigidity of the arm 81.

  In the preferred embodiment shown in FIGS. 14-17, the peripheral groove has a constant cross section, but the peripheral groove has a gradual cross section with a slope or step, or is stepped as seen in FIG. FIG. 20 shows two examples of steps 89A, 89B, 89C expanding from the frame 80 on the one hand and steps 89D, 89E, 89F narrowing on the other hand to the frame 80. In the first case, the bundle tangent to the pins at different positions, i.e. the bundle F1 with the opening angle α1 when using the smallest pin 84 or the bundle F2 with the opening angle α2 when using the largest pin 86, When the largest pin 86 is used, it is not opened more than the bundle F3 having the opening angle α3. Therefore, when using the spreading step, it is better to adjust the position of the axis D with a very small step, whereas when using a narrowing step, the pin with the same diameter is adjusted with a larger step. I do.

FIG. 21 shows an insertion clasp 90 that may be used in place of such pins or to hold one or more pins. The loop 90 preferably has an oval body 92 between two lugs 91 that are spaced apart by a width EP, which is slightly larger than the local thickness of the plate 60. In one direction, for example, an oval body 92 having an oval or oval cross section has a support surface 93 where the dimension is minimum and a support surface 94 where the dimension is maximum. FIG. 22 shows the insertion of the oval body 92 into the peripheral groove 82 where the dimension is minimal, this minimum dimension being slightly less than the local width of the groove 82 and the subsequent simple The holding of the oval body 92 in the block position by pivoting is shown, wherein the lugs 91 are now positioned on both sides of the plate 60 and the loop stop 90 leans against the arm 81 or presses the arm 81.

  FIG. 23 shows the variation of FIG. 12 with a rigid jewel holder block guided by a rod and adjusted against a spring by a screw.

  FIG. 24 shows a jewel holder slide that slides linearly with respect to the plate 60 and achieves retention in place by pinning on the plate, as seen in FIG. FIG. 26 shows a similar movement, where the slide has a rack that interacts with a toothed wheel secured with a jumper. FIG. 27 shows a variant in which the jewel is carried by a toothed wheel that works with another toothed wheel fixed with a jumper.

This guide element 10 consists of a jewel bridge 340 that holds the jewel 34 or directly consists of a jewel 340. The jewel bridge 340 or the jewel 34 is irreversibly fixed to the clock mechanism plate or bridge after the position adjustment, particularly by laser welding or the like. In this case, the movement 200 includes a gap 381 for guiding the pivot 38 and a guide 45 for guiding the eccentric finger 41. The pivot 38 and the finger 41 use the lever 37 after the final fixing of the jewel 34. Placed in place.

  The present invention also provides the movement 200 with a guide 381 for receiving and guiding the pivot 38 and a guide 45 for receiving and guiding the rotating shoulder 46 of the eccentric finger 41 at the height of the plate or bridge. Also related. The movement comprises at least one watch mechanism 100, which itself comprises at least one reference watch wheel defining a reference axis, and a first watch wheel, the position or geometry of the first watch wheel.
